Great product. Does the trick in helping me to get to sleep faster and stay asleep. I travel a lot for work and I have been sleeping so much better in hotels, which has historically not been the case. As usual, another great product from RSP.

Didn't know posting another review would delete my previous so here's an edit: Not sure why my (last) review was found unhelpful by 3 people but I honestly recieved this product containing what I believe had to be RANCID vitamin D. Upon opening the bottle I noticed a somewhat "off" odor but having used this product in the past I figured it was still okay. WRONG! It gave me the s***s for a week! If that's what you're into then by all means, purchase this product and be ready to spend an hour playing 20 questions for a refund which you can apply toward another brand and have to pay shipping for... BTW I'm only logged back on so I can rate/review the Amino Focus which came in the same order. Found a mysterious chunk of something brown with what look like little hairs on it in the powder! I honestly looks like a dried up scab that fell off someones hand but hopefully it's a raw ingredient somehow. Regardless, due to these issues I will no longer be purchasing anything from RSP. They have lost me as a customer after 2 years of being satisfied with their stuff.

Nothing. Zero. Didnt improve my sleep AT ALL.

Just finished my first bottle, currently ordering more.. i love it. I have problems sleeping and i need vitamin D, so those are two main reasons i purchased it. i would totally, recommend it.

I got this product because I love RSP and their no B.S. products. I have a ton of problems sleeping and that causes alot of issues in general with ones body. I began taking these pills and after awhile my body began to absorb them and give me a more restful sleep. I still do not sleep well but, for some reason, I will wake up regardless of how much sleep I got in a more well-rested manner.

I didn't get much from this one.. Search Google for "testotrials" if you want something that works good.

I love this stuff! I have tried countless sleep help methods. This lets me sleep deeply but wake up feeling refreshed, not groggy!

I really like this product! Felt more rested in the morning! I will continue to use this product going forward.

Love this product ! Helps tremendously when it come to sleep and muscle recovery will continue to use

useless product. no changes and no results.

I’ve tried a few different supplements very similar to Z-Elite, but I definitely found the best results with this product (I’ve been using it for about 2 months). Also I loved how it was very light on my stomach and no crash or anything. Overall I say a very good supplement.

This is by far my favorite product from RSP. Z-elite gives me such a noticeable deper sleep. I️ wake up feeling well rested and ready to start the day. I️ definitely recommend this

I have been taking this produce every night for around two years now. Works great and would recommend it to anyone
